What Is Trabecular Metal?

An accomplished spinal surgeon, Paul Saiz, MD, has served as a speaker and faculty member at numerous seminars, conferences, and continuing education courses. Dr. Paul Saiz has taught several such courses on the spinal use of trabecular metal.

Designed for use in orthopedic and dental implants, trabecular metal approximates the properties of bone. Its 80 percent porous construction allows for surrounding bone to grow into the structure with as much as three times more effectiveness than traditional implant coatings. The compound further supports the growing in of natural bone (in-growth); in that its pores are consistently sized and fully interconnected. Studies have demonstrated that this construction allows for better filling in of available pores compared to other materials.

Also constructed to be stable in daily use, the compound features nanotextured construction with a high friction coefficient. This encourages a stronger initial fit as well as continuing tightness. After four weeks, study subjects showed a bone interface strength approximately double that of sinter-bonded bead implants. This is further enhanced by the compound’s low elastic modulus, which gives the material the same stiffness as bone (making it more bone friendly). Chemically and biologically stable as well, it stands out as a safe and more effective alternative to traditional implant substances.
